The HP Spectre Folio is a laptop made of leather. As in: you cannot remove the leather, because the leather is part of the case.
It's a premium ultraportable 2-in-1 with HP's Tilt Pen and 4G LTE. A 4K display option will be available, but not at launch. Prices start at $1,299. The "product exterior and outer keyboard is 100% genuine full grain leather as of 9/18/18" but it looks like corrected-grain to me, with no imperfections and a lot of homogenization. The proof will be in the patina: what will it look like after a few months of daily use?
